The goal of this study is showing the effects of bone mass density and bone–implant interface characteristics onmaximum stress in mandible bone. A 3D nonlinear finite element analysis has been done on a planted titanium cylindrical implant with frictional contact of bone–implant interface. Considering the coulomb frictional contact, maximum Von Misses stress increases in cancellous bone, prominently. It has been shown that cortical bone stress is more sensitive to friction coefficient than cancellous bone. Bone mass density changes with variation of bone strain in specific spans of the strain. Raise of bone mass density in cortical bone increases the stress of cortical bone and decreases the stress of cancellous bone. Sensitivity analysis shows that cortical bonestress is 2.7 times more sensitive compared with cancellous bone.

There are various ways to investigate the buckling phenomenon in a steel compression member. Among these methods experimental formulas, semi–empirical formulas, closed form solutions, classic methods based on differential equations and also numerical...

Natural gas TEG–dehydration is the process of removing water from the gas stream to lower the dew point of natural gas. Water is the most common contaminant of hydrocarbons and can form hydrates, which may block valves and pipelines. Also water can...

Parametric study is performed by sensitivity analysis (SA) for solid oxide fuel cells (SOFCs) on an artificial neural network (ANN) model of the SOFC performance. The ANN model have been used to predict the SOFC performance exactly and then the...

One of the challenging issues in modern civil engineering analysis is the typically large number of random quantities defining the input and system parameters. One approach to making such problems tractable is to identify the most important sources...

There are many ways to produce the hydrogen. A way is through steam reforming. Because in this method CO2 presents as an impurity with hydrogen, hence CO2 should be removed. Since stripper column is keyequipment in purification process, thus, in this...
